Distal Pen arms for Eggbot

The Eggbot kit mounts its pen at the end of the pen arm, in a piece called the "distal" pen arm.

The standard distal pen arm has a hole that fits Sharpie Ultra-Fine pens, and other markers of similar size. It also has a nut and nylon thumbscrew to fix the pen in place.

The wide-hole version looks the same, except that it has a slightly larger hole that fits a standard (so-called "fine point") Sharpie marker, or other markers of similar size.

We also offer a fully blank distal pen arm, in case you want to drill your own hole and/or mount something that requires a different mounting scheme. The blank version does not have a nut or thumbscrew, but instead just a small pilot hole.
